We use slope daily in site grading, but it's nice to see the basic math layout here.

wait, why is the constant term the y-intercept again? i forgot the rule

@Min-ji Because the y-intercept is where x is 0. So y = -3(0) + 4, which leaves just the 4.

A bit too advanced for my Grade 4s, but I love that tiny teacher note!

My eighth grader is practicing these exact linear equations tonight. Perfect timing.

@Nguyen Anh same, but my score was only 7 out of 10.

The distinction between the coefficient of x and the constant term is explained so clearly.
